Wet Exhaust Hump Hose Bellows, Reinforced VHT Blue Silicone 350°F, 4.00 Inch ID, Single Hump, 6.00 Inch Long

For a 4.00 inch inside diameter connection, this bellows matches that ID and it is 6.00 inches long with a single hump meant to take up movement and vibration in a wet exhaust run.

This reinforced silicone hose can handle constant temperatures up to 350 degrees Fahrenheit, which makes it a good choice for high-heat areas in marine wet exhaust systems.

Stainless steel clamps come included with the hose. For best results, each end needs a minimum of two clamps that are at least half an inch wide. T-bolt clamps at three-quarter inch wide or constant torque clamps at five-eighths inch wide are the recommended options if you ever need replacements down the road.
